Application filed December 29, 1924. Serial 110.758,?66;

To all whom it may concern;

Be it known that I, HENRY WV. STEEGE, citizen of the United States, residing .at lVaterloo, in the county ofBlackH'awk and State of- Iowa, have invented certain new and useful Improvements in Stanchions of which the following is a specification.

My invention relates-to improvementsin stanchions such. as are used as parts ofthe 'cattle furniture in stables, and=the object of my improvement is to provide impro-vedoppassing vertically through said supports;

These objects I haveaccomplished'by the means which are hereinafter I described and. claimed, and which are illustrated in the accompanying drawings. it being understood 257 that minor changes or variations in any of being removed'or broken away. Fig. 5'is a top plan of the top operating means 'of'the' and itsother'end-secured in a hole in the The numeral 12 denotes a horizontal-pipemounted in couplings 13 011 the tops of spaced tubular standards 14 whose lower ends are embedded in or otherwise-'fixed in' a floor or base 6. A pair ofspaced couplings or sleeves 11 are mounted medially on the the parts or their arrangements will nevertheless be covered by my invention.

In said drawings Figs. 1 and'2 are re-' spectively rear elevations of my improved stanchions in a closed and, an open position. Figs. 3 and at are respectively front elevations of said stanchions in a closed'and in an open position,- the upperparts' only being shown, other parts and'the supporting means stanchions.

pipe 12..and .ha-ve apertured lugs to which are connected short" chains 10 whose lower ends are brought together obliquely and connected to a ringed hook 9 which in turn has its depending hook inserted in a medial hole 8 in a small hollow housing 7.

The numerals 1 and 2 denote a pair of stanchions whose lower ends are recurved toward each other and hinged together on a pintle 3 to which is connected one end of a ,short chain a whose lower end is connected tola. ring bolt. 5 embedded in the floor 6. The upper ends of the stanchionsware' roc-urved toward each other and flattened plugs'15 are. mounted and secureddn their ends to project thereabove inclinedly.. On= these parts 15 are fixedjas by. welding'or otherwise like fiattened arms17g and 18: re-

speotively to be apposediinparallel and in contact to slide back and forth upon each other, thegarms being curvedion :an arc whose radius centers in the pintle 3.. The housing 7 is open atopposite ends in the plane which passes vertically through the standards 14%.

and the said arms 17.- andj18xare passed through this housing.

Referring first to the rear elevations shown in said Figs. 1 and 2, the numerali23 denotes a short rock-shaft mounted in, a pair: of

alined'bearing apertures in op-posite front and rear walls ofgthe l housing; 7'. to: p1ioje ;.:t--

oppositely therefrom. On these oppositely projecting ends of the rock-shaft are fixed short cranks '22 and 29 respectivelyof the same lengths. A link 20 is pivotallycon: nected at its endsat 1 9 and'21 respectively to the member 15 on the stanchion 1 and to the said crank 22, and:a stop pin on the hous- 1i1g limits downward movement of the like link-30 has its opposite ends pivoted respectivelyto the member- 15' on the stanchion 2 andthe crank 29- by means of'pintles 26 and 31; A. coiled. spring 27 is mounted on the'pintle 26 withone-end engaged with. a-

headed pin 28-fixed inthesaid' member 15 link- 30. I

The numeral- 25 denotesa flanged plate se cured on the front of 'thediousing 7 to pro-- ject there'fromatone end over. the member 15"on the stanchion l. The horizontalflange of this plate-serves as a -guardover the crank 29 to prevent accidental impacts, as=froma cows" horn, from rocking down the crank stanchions may be thus spread apart by the operator when in front of the stanchions by pushing downwardly the connected crank 29 and link 30 past a dead center whereupon the relatively heavy stanchions 1 and 2 in having thus been caused'to pass outwardly beyondtheir centers of gravity will swing outwardly farther to the limits imposed by the connections of the links 20 Land 30'to the plug-members 15. In their opened positions, however, the crank and link connections cannot pass beyond a dead center be cause of the stopping of the crank 29 at the stop-pin 24- and the stopping of the crank 22 by the stop-pin 32. The stanchions are yieldingly held apart by the spring 27. In case the operator is standing'in the rear of the stanchions, he may open the stanchions by manually swinging upwardly the connected crank 22 and link 20 past a dead center so that the stanchions in likewise spreading apart beyond their centers of gravlty will then swing outwardly to their limits of movements.

The stanchions are closed together by merely swinging them towards each other, in so doing rockingthe rock-shaft 23 reversely bymeans oft-he connected links and cranks already described, and the spring 27 yieldingly holding the parts intheir closed positions but not passed beyond a dead center on either side, so that they may be reopened in the way already described. These operating parts in both opened and closed positions are so held or interlocked that the animal cannot release them to cause an opening of the stanchions.

Particular attention is invited to the 1nan ner of supporting or suspending the stanchions from the plpe support 12 to cause the stanchions to swing back into a normal pos1- tion in the vertical plane of the support when displaced or rocked horizontally. This is effected by hanging the housing 7 medially on the downwardly: converging chains 10 which hang insaid vertical plane, and which tend to yieldingly resist rocking parallel relation mounted within said housing to slide past each otl er, and resiliently controlled operating connections movably connected to and between said housing and the upper parts of the stanchions, operable to be moved past their dead centers and swing the stanchions t0 and fro to closed and opened positions and to yieldingly resiliently lock them in both of said positions.

2. In combination, an elevated support, an open-ended housing suspended swingingly from said support, a pair of stanchions hinged together at their lower ends and having their upper parts recurved to slide past each other and through said housing, a rock.- shaft mounted in said housing, cranks on opposite ends of the rock-shaft, links con nected between said cranks and the adjacent stanchions, a guard flange mounted fixedly on said housing above one connected crank therefrom to be retained yieldingly in a certainvertical plane, a pair of stanchions below said housing, hinged to ether at their lower extremities and having their upper parts bent. inwardly slidingly past each other in an arc of a radius from said hinged connection, said arcuate parts traversing said housing, a rock-shaft mounted in said housing having cranks on its opposite ends, links pivotally connected between said cranks and the adjacent stanchions, means for nreventiim the passage of the connected cranks and links past their dead centers in certain directions, and a resilient connection between. one of said stanchions and one of said links tendin" to yieldingly and resiliently retain the stanchions in either their open or closed positions.

In testimony whereof I aliix my signature.

HENRY werensn.
